BuiltWith vs Wappalyzer vs TechLeads.fyi: Complete 2026 Comparison

If you’re in the market for a technology lookup tool, you’ve probably come across three main options: BuiltWith, Wappalyzer, and TechLeads.fyi. Each serves a similar purpose—helping you discover what technologies websites use—but they approach it differently and serve different use cases.

In this comparison, I’ll break down the honest pros and cons of each platform so you can make an informed decision for your specific needs.

What Are We Actually Comparing?

Before diving into the comparison, let’s be clear about what these tools do. All three platforms detect technologies on websites—things like:

• Content management systems (WordPress, Shopify, Webflow)
• Analytics tools (Google Analytics, Mixpanel, Amplitude)
• Marketing automation (HubSpot, Marketo, Mailchimp)
• Development frameworks (React, Vue, Angular)
• Hosting and infrastructure (AWS, Cloudflare, Vercel)
• E-commerce platforms, CRMs, payment processors, and much more

The differences lie in database size, pricing, features, and what you can actually do with the data.

BuiltWith: The Enterprise Incumbent

BuiltWith has been around since 2007, making it one of the oldest players in this space. They’ve built a solid reputation, particularly among enterprise customers.

What BuiltWith Does Well

Historical Data: One of BuiltWith’s unique strengths is historical technology tracking. You can see when a company adopted or dropped a technology, which is useful for market research and competitive analysis.

Large Database: They claim to track technologies across hundreds of millions of websites. The coverage is solid, especially for popular technologies.

Established Reputation: Being in the market for nearly two decades means they’ve refined their detection methods and built trust with enterprise buyers.

Where BuiltWith Falls Short

Pricing: BuiltWith is expensive. Their Basic plan starts at $295/month, and Pro is $495/month. For teams that need multiple users or advanced features, costs escalate quickly.

Interface Complexity: The platform can be overwhelming for new users. There’s a learning curve to getting the most out of it.

Limited Lead Generation: While BuiltWith provides technology data, the actual lead generation capabilities—like contact enrichment—are limited compared to more modern alternatives.

Best For

BuiltWith is best suited for enterprise teams with substantial budgets who need historical data tracking and don’t mind paying premium prices for an established tool.

Wappalyzer: The Developer Favorite

Wappalyzer started as an open-source browser extension and has grown into a commercial platform. It’s particularly popular among developers and technical users.

What Wappalyzer Does Well

Excellent Browser Extension: Wappalyzer’s Chrome extension is arguably the best in the business for individual site lookups. It’s fast, accurate, and the free tier is generous for casual use.

Developer-Friendly: The technology definitions are open source, and the platform has a technical, no-nonsense approach that developers appreciate.

API Access: For technical teams that want to build custom integrations, Wappalyzer provides solid API documentation.

Where Wappalyzer Falls Short

Smaller Database: Compared to BuiltWith or TechLeads.fyi, Wappalyzer’s website database is smaller (around 100 million websites vs. 300-450+ million).

Expensive Pro Plans: Despite the smaller database, Wappalyzer’s pricing isn’t cheap. Pro starts at $250/month, and Business is $450/month.

Not Built for Lead Gen: Wappalyzer is fundamentally a technology detection tool, not a lead generation platform. There’s no built-in contact enrichment or CRM-focused workflows.

Best For

Wappalyzer is ideal for developers, technical marketers, or anyone who primarily needs browser-based lookups and API access rather than bulk lead generation.

TechLeads.fyi: The B2B Lead Generation Focused Alternative

Full disclosure: this is our platform, so I’ll be as objective as possible. TechLeads.fyi was built specifically for B2B sales and marketing teams who need to turn technology data into leads.

What TechLeads.fyi Does Well

Largest Database: With 450+ million websites indexed and 3,600+ technologies tracked, TechLeads.fyi offers the most comprehensive coverage available.

Built for Lead Generation: Unlike tools that are primarily technology detectors, TechLeads.fyi was designed from the ground up for B2B prospecting. You can build lead lists, apply filters, and export with contact data.

Contact Enrichment: This is a big differentiator. You don’t just get a list of domains—you can enrich your exports with decision-maker emails, phone numbers, and company information.

Competitive Pricing: At $79/month for Pro, TechLeads.fyi is 3-4x cheaper than comparable plans from BuiltWith or Wappalyzer. This puts enterprise-level technology data within reach of startups and SMBs.

Data Freshness: The database is refreshed regularly, and staleness indicators show you how recent each data point is.

Where TechLeads.fyi Falls Short

No Historical Data: Unlike BuiltWith, TechLeads.fyi doesn’t track historical technology adoption. You see what’s on the site now, not what was there six months ago.

Newer Platform: Being newer to the market means fewer integrations and less brand recognition compared to established players.

Best For

TechLeads.fyi is the best choice for sales teams, marketing agencies, and B2B businesses that need to generate leads from technology data without paying enterprise prices.

Pricing Breakdown: What You’re Actually Paying

Let’s talk money, because this is often the deciding factor:

BuiltWith

• Basic: $295/month

Wappalyzer

The price difference is significant. For the cost of BuiltWith Basic, you could have TechLeads.fyi Pro for nearly four months.

Which One Should You Choose?

Here’s my honest recommendation based on different use cases:

Choose BuiltWith if:

• You have an enterprise budget ($500+/month is fine)
• You need historical technology tracking
• You’re doing market research rather than lead generation
• You value an established brand name for stakeholder buy-in

Choose Wappalyzer if:

• You’re primarily a developer or technical user
• You mainly need browser-based individual lookups
• API access is your primary use case
• You don’t need bulk lead generation features

Choose TechLeads.fyi if:

• You’re in sales or marketing and need to generate leads
• You want contact enrichment included
• You need the best value for money
• You’re a startup, SMB, or agency that can’t justify enterprise pricing
• Database size and fresh data matter to you

The Bottom Line

All three platforms can tell you what technologies a website uses. The question is what else you need.

If you just need occasional lookups, any of them will work. If you need to build sales pipelines from technology data with contacts included, TechLeads.fyi is purpose-built for that at a fraction of the competition’s price.

My suggestion? Try the free tiers of each and see which fits your workflow. For TechLeads.fyi, you can run 50 free searches to test the data quality before committing.
